For about a month now I have been experiencing an uncomfortable, sluggish feeling in my chest that can go on for hours at a time. Occasionally (about once a day) it gets really painful.
I looked up the NHS website, and my symptoms seem to match that of angina (neck pain, tiredness, breathlessness, pain in left arm, etc).
However, I am only 14 and I am of a healthy weight. I admit that I do not exercise a lot. I didn't think that angina could affect people my age.
It used to be that I could just grit my teeth and bear it, but it's beginning to affect my concentration in school.
